    Hr is for only reactant and h solution stands for the whole solution present which implies presence of reactant and product Delta h= hp-hr This example will help you https://doubtnut.com/question-answer-chemistry/from-the-following-data-mark-the-option-s-where-delta-h-is-correctlt-written-for-the-given-reaction--18931254

    I wrote dhr as enthalpy of rxn

    eduncle-logo-app

    yes, dhr defines only for reactant and dh solution is for the reaction and product combined

    eduncle-logo-app

    yahan pe dHr is heat of rxn na?

    eduncle-logo-app

    yes

    eduncle-logo-app

    yahan pe dono same hona chye na?

    eduncle-logo-app

    no, I think you're confused with question. please watch the video for more details. the answer by balancing the following is ab and c

    eduncle-logo-app

    i did the balancing sir. Heat of solution =Heat if hydration +Heat of Heat of ionization. Already value of heat of solution is given in qs.

    eduncle-logo-app

    my qs is already value of c is given in qs as it is equation for heat of solution. why we need to find it differently.

    eduncle-logo-app

    the question is quite twisted as the examinar wants to see your judgement. you are here expected to find the correct options. all a B and c are in aq state or gaseous but when you look at d they are in aq state which is incorrect. hence the twisted part

    eduncle-logo-app

    a option is also all aqueous state.

    eduncle-logo-app

    a is acid base reactants whereas in d they are charged species and also no supporting calculations for option d

    eduncle-logo-app

    sir just tell me one thing how the heat of solution of HA(g) is different from HEAT of rxn of c.? For both equation are same.
